And for completeness, dumps from the wonderscan crystal would be nice too laugh
We were only able to find the bit of code in ram that disabled the system rom, nothing of the system rom itself. Also attempts to turn it back on didn't work frown

Friendly 2018 reminder: I'm still desperate to get the Bandai Wonderswan+Color IPLROMs (system boot ROMs) dumped. I'll contribute hardware+funds to anyone who can try to help make this happen.

The Olytext 20's manual is on the FTP now - unfortunately there are almost no technical details, it's mainly about the Olytext application.

I got the Olytext 20 and the Brother SK-64 that yielded the ROMs I posted last year in this thread. This one is working so I can show more screenshots from the machine. On the word processing disk I have is a pared down version of CP/M that allows the user to access the command line but has the usual utilities (PIP, STAT, FORMAT ... ) conflated into a menu driven affair.

Is that little "OLY" on the right side of the menu title simply a special character or an indication of graphics capabilities?

It's probably part of the font, but it's hard to tell for sure from just screenshots.

Motivated by having the Olytext 20 up and running, I brought out the Olytext 30 again, presented here. The power switch is faulty, and I had no EGA monitor handy, so I bridged the switch and changed the EGA card for an 8bit VGA one (cf. http://forums.bannister.org//ubbthreads.php?ubb=showflat&Number=81246#Post81246)

Please forgive the crappy screenshots, the monitor is somewhat inaccessible atm ...

The VGA card dominates the POST screen, so I have no idea what the original EGA would look like (its ROM is dumped though and included in the Olytext 30 files). I like it because its font is different from more run-of-the-mill cards. You can still see the AEG Olympia boot message.

The Olytext 30 needs an XT keyboard, an AT one yields an error message on the POST screen, way before the message of the Cherry keyboard driver appears.

Starting the Olytext word processor ... it won't run without its Z180 coprocessor card.

And here it is in all its glory, looking a lot like the CP/M based Olytext II from the Olytext 20:
